We are in agreement then. What typical Americans label radical left is not at all radical in most other rich nations and what we call right wing is considered extreme right wing in most other nations. You haven’t been radicalized, what has changed is the views of the average voter. When I talk about radicalization of white men I mean in terms of where they are in absolute terms, not how far from the center they are.
Holding mostly centrist views from my childhood makes me "radical left" now as politics have swung hard to the right. I don't believe your notion of what radicalization means to be correct.
